Formula of a sphere surface area

WebCurved Surface Area As the Hemisphere is the half part of a sphere, therefore, the curved surface area is also half that of the sphere. Curved surface area of hemisphere = 1/2 ( 4 π r 2) = 2 π r 2. Base Area. The base of the hemisphere is in circular shape. As we know by the formula of area of circle, Area of base = π r 2. Total Surface Area Web1.Slice a sphere into thin circles (or rings if you hollow them out) The sum of the circumferences of all the circles forms the surface area of the sphere. Since the formula of circumference is 2 π R, the sum of the circumferences would be 2 π ( R 1 + R 2 + R 3 +... + R n) My son draws the radii beside each other and concludes that their sum ...
